title: Post-traumatic intrahepatic pseudoaneurysm: diagnosis with helical CT angiography and management with embolization.
abstract: The authors report a case of liver trauma with hematoma complicated with a pseudoaneurysm. The latter was suspected on day 7, with a monophasic helical CT and was demonstrated with helical CT angiography. Arteriography confirmed the lesion and showed an associated arteriovenous fistula, unsuspected on helical CT. The pseudoaneurysm was managed with transcatheter embolization, completed with percutaneous embolization because of vascular spasm.
